SPECIFICATION forming part of Letters Patent No. 246,676, datedSeptember 6, 1881.

Application filed July 8, 1881.

To all 'whom it may concern:

Be it known that I, HENRY HrTcHcocK, of Lyons, Ionia county, Michigan,have invented an Improvementin Frames forRevolving Hay- Rakes, ofwhichthe following is a specification.

The nature' of this invention relates to certain new and novelimprovements in the coilstruction of frames for revolving hay ralzes,tedders, Sac., the object of the invention being to construct a framewhereinthe necessity of employing caster-wheels or tilting frames isavoided; and to that end the invention consists in the peculiarconstruction and arrangement of the parts, all as more fully hereinafterset forth.

Figure 1 is vtop plan. the main driving-wheel.

In the accompanying drawings, which form a part of this specification, Arepresents the bars which compose the frame ofthe machine, which aresecured together substantially inthe form shown, and braced at thecorners by the brace-rods a, which give additional rigidity to theframe. To cach side of the frame are pivotally secured the plates B atone end, which carry stub-axles C, upon which the tractionwheels D aresecured, the platesB being capable of an adjustment upon the frame bymeans of curved slots in the said plates concentric with the centers ofthe pinions F, so that the frame may be raised or lowered, ascircumstances may require. To theinner side ofeach ofthe traction-wheelsis secured the internallytoothed gearwheel E, which engages with apinion, F, upon the shaft G, which is journaled in proper bearingsacross the frame, the connection between the pinion F andthe shaft being through the medium of a ratchet or clutched Fig. 2 is elevation of (Nomodel.)

pinion of any of the known construct-ions. To the shaft Gr are securedthe rake or tedder teeth H, which revolve with the shaft entirely withinthe frame and nearly upon a line with the two stub-axles, as shown.

Draft is applied to the machine by means of the shafts or tongue E.

By this construction I materially lessen the Weight ofthe machine, whileI secure greater strength and rigidity ot' parts over the old manner ofbuilding.

By means of the plates B, connected to the frame and to the wheels, asdescribed, the position of the frame can be readily adjusted withoutalteringthe positions ofthe pinions 11 in relation to the driving-gearwheels E.

What I claim as niyinvention is- 1. In a revolving hay rake or tedder,and in combination with the frame A thereof, the plates B, carrying thestub-axles C,said plates being pivotally hung on the revolving shaft Gand provided with slots concentric with the center of said shaft,whereby the position of the frame can be adjustedin a radial line fromsaid shaft, substantially as specified.

2. Theframe A, wheels D, and driving-gear Wheels E of a revolving hayrake or tedder, in combination with the shalt G, pinions F on saidshaft, stub-axles C on the platesB, and the plates B, said plates beingpivotally hung on the shaft Gr and provided with slots concentric withthe center of the same, substantially as and for the purpose specified.
